This here is a guide that a Neopets user told me over the Neoboards maybe... one or two years ago? She told it to me quickly, too. Anyway, I don't remember her username, I really wish I do. I recall visiting her profile a few weeks later and seeing "This user has been frozen." This ONLY works with Firefox, which can be downloaded at http://www.mozilla.com/ First off, you want to download NoScript, found here: https://addons.mozilla.org/en-US/firefox/addon/722 Now go to the topic you want to spam. Type in the message you want to say and instead of clicking "Post Your Reply," right-click it and click "NoScript > Forbid Neopets.com" (Yes, that gear thing is most surprisingly my mouse cursor) Make sure to quickly press the "Post Your Reply" button over and over again after doing the last step to create multiple posts.
I don't know, some people like to spam the NeoBoards on other accounts. It is an easy way to get banned, but some people get away with it... it's very risky. I saw a Neoboards Spammer on the DL page so I decided to put this up since it seemed OK.
